[0003] The backlight module is an important part of an electronic device. At present, the backlight module of portable electronic devices such as smartphones usually adopts a side-type backlight module, that is, the light emitted by the light source enters the light guide plate from the side of the light guide plate, and is guided by the light guide plate. Finally, it provides backlight for the display panel of the electronic device. However, since the light source and some related structures of this side-type backlight module need to be arranged on the side of the light guide plate, it occupies a large non-display area, which is not conducive to narrow The realization of frame and full screen, how to shorten the width of the backlight module in the non-display area without affecting the normal display of the backlight module and the display panel, has become the focus of attention.

The invention discloses a backlight module and an electronic device. The backlight module comprises a light guide plate, a light source, a dodging element and a shading fixing layer; the light guide plate comprises a light incident surface and a light emitting surface, the light source and the light emitting surface are arranged at an interval, the dodging element is arranged on the light emittingsurface of the light guide plate, and the end, close to the light incident surface, of the dodging element is located in a non-display area; the shading fixing layer is arranged in the non-display area, arranged on the side face, close to the light incident surface, of the dodging element and the side face, away from the light emitting surface, of the dodging element and used for fixing the dodging element and preventing the non-display area from light leakage. Therefore, fixing elements fixing the dodging element can be saved, the width of the non-display area occupied by the backlight module can be reduced, and the phenomenon that light leakage occurs in the backlight module can be avoided.
Description
